Carbon dioxide, you’re under arrest!


Carbon dioxide emissions aggravate global warming. The Centre’s weekly analysis introduces Carbon Capture and Storage (CSS) technology, which can remove and store carbon dioxide, and its use in power generation. The article indicates that applying CSS technology requires geography’s blessing and cost consideration, and also introduces its potential development in China.


Policy perspectives on fuel mix


The Environment Bureau has launched a public consultation on the future fuel mix for electricity generation in Hong Kong, of which the suggestion to purchase electricity from Mainland power grid has aroused public concern. The Centre’s weekly analysis examines the energy policy and market operation in the Mainland, with an aim of providing the public with a better insight into energy sources, stability and pricing of electricity supply in the Mainland.

A dripping tap


The Government is negotiating with the Guangdong Authorities on a new agreement for the supply of Dongjiang water to Hong Kong, as the current one is about to expire. The Centre’s weekly analysis looks into different measures to improve water utilisation and explore new sources of water supply, by examining a number of factors, including global water distribution, water supply policy in the Mainland and water consumption in Hong Kong.

Turning a grey sky blue


Hong Kong has long been plagued by air pollution. The Centre’s weekly analysis examines the causes of air pollution and identifies the sources of pollutants. The article also points out that air pollution is a transboundary problem, and suggests regional governments to enhance cooperation and turn a grey sky blue.

Nuclear Energy or not?


Hong Kong has been negotiating with the Mainland on importing more nuclear energy, but the panic caused by the Fukushima nuclear incident has yet to fade away. The Centre’s weekly analysis examines local fuel mix for electricity generation and compares nuclear energy with other sources of energy in terms of levels of carbon emission and pollution to the environment, costs of power generation and safety etc. It ponders on how we could move forward to develop renewable energy to balance energy efficiency, safety and costs control, as well as meeting the long term demand on energy consumption

Charging as a means to waste reduction?


Waste charging could be a feasible alternative to landfill expansion, which has sparked debate in Hong Kong recently. The Centre’s weekly analysis delves into the waste charging initiatives taken by Singapore, Taiwan and South Korea and measures their effectiveness. It also studies the effects of recycling and the construction of additional incinerators in Singapore. The analysis identifies potential problems facing the proposed volume-based waste charging scheme, and suggests the Government to map out waste reduction policy after thorough consideration.

Bottleneck in recycling


The Government suggests producers to take responsibility on glass beverage bottle recycling, aiming to recover as much as 70% of waste glass. But glass takes up only a small percentage of municipal solid waste, and the limited uses for recycled glass can hardly achieve the best value for money. The Centre’s analysis for this week discusses the difficulties facing local recovery and recycling industry, with a view to resolving this environmental problem from a practical point of view and through diverse initiatives.
